coffee by 9W2WF..thanks it keep our eyes openLast Sunday 27 June 2010, few of us gathered at Mares Club House to join this activity.To build a linear power supply.Class was conducted by Mr.Mansor @ 9W2TTC.In this class we will learn exactly from the 3 pin plug 240AC to the final output of 13.8V that will be feed to our equipment.Mr.Mansor on action...this is the best circuit..the "ingredients" for our soup...fresh and selected items onlyheat sink banks from junkyard..

Even though the class only going on for few hours, but it good for me, I can sharpen my skill again. Well it been almost 11 years since I left my technical school (SekolahMenengahTeknikKulim).Mr Mansor elaborate us very detail of each and usage of every component. Why it should be this value and rating. (opsss...now I know why it burnt!)

The block diagram of the power supply now is in our head. For upcoming classes, there should be more fun...seeing from all the belongings of Mr.Mansor I could not imagine the condition of his base. I only could imagine my base...(messy..very messy)from previous project belong to 9W2UIA

need a modification...add transistors, capacitors..etc..Well folk, if you are interested in electronics..make a pit stop at Mares Club House every forth week of Sunday monthly.

Compaq? with terminal?what..with ampere gauge and voltmeter?

ohh...finally the content..Mr.Masor still maintain the floppy drive..wonder why?for logging?

So. see you guys on next class...
